To all whom 'it may concern: V

Beit known that I, FRANK lP.-IllAfnis",f a'

citizen-f the United States, residingin thev borough of Brooklyn, county of Kings, and

State of New York, have invented certain new and useful Improvementsin Tire-Protectors, of which the following is a specication.

My invention relates to'tire protectors of that class in which the protector isy inserted loosely'between the shoe or casing 'and the` air-tube of a double tube tire.

The'object of my invention is to provide an improved construction of this character,- so as to afford an increased" safeguard against injury to the air tube or shoe, even inthe extreme case of the tires collapsing,

say lon account of la leaking valve.

A specific' embodiment of my invention will now be described in connection with the` 4 is a sectional view tiereof yon line 4.-4 of Eig. 3. l The improved protector com rises a sheath made of cxible fabric an formed with transverse pockets, and resistant joint-' ed strips contained in said pockets. vIn the particular construction shown, the sheath comprises four layersthe outer or exposed layers A, A being as a rule relatively thin,

and inelastic (consisting, for. instance of duck) Whilo'the inner or unexposedlayers' B', B, are made of thicker and softer, that is, somewhat elastic material, such as dan, nel. The four layers are sewed together at' intervals by transverse lines of stitchingC, and are of a width preferably more l"than half the transverse inner circumference of the shoe or casing D .(see- Fig.' 2) while the` length of the strips A, A', 13,13', is equal to or slightly;v greater than' the longitudinalinner circumference of the shoe D. The

sheath ma thusy be interposed between lthel shoe D 'an the inner tube E in such a manner that lthe inner tube will be at no 'point in contact with the inner surface o :the

shoes treadlp'ortion. The ends-.of the sheath will genera y I be overlapped. slightly, and may -shift or'slideon eac other,l when they.

ingpierced or injured-by the reach the lowermost lposition duringthe roftation of the wheel.

F indicates the wheel rim which may be 'of-any usual or approved construction.

y.The seams C .form transverse compartmentswithin the sheat and in each of these com artments I place a strip consistin of meta plates G which'v may be rectan'gu ar 'as shown or tapering, and which arel hinged to eachother as at Gr', to swing about axes which' range c rosswise of the strips, andV therefore lengthwise of theprotector. vuiicient space is left between the edges of 'adjoiningstrips to allow them to accommodate themselves to the variation -in diameter, since obviouslythe central portion of thepiotector iswhen in use of a greater diameter than' its' edge portions.. The frictionof the metal against the soft .layers B, B', may be suiicient to 'prevent thestrips from sliding out of their'pockets,

ockets or:

f but ifdesired, special means may be emiplo'yed to guard a ainst this contingency,

t wil be observed that the free ends ofi thus avoiding the perforating tendency'they would have 1f pointed. Another feature of `considerable importance is the .tact that the the last plates Grof each strip are rounded,

lengthof the strips is materially less than -f the width of the protector, so that the sheathhas at each side a free and extremely tlexible marginal iiap H, containing no metal plates. The advantage of this construction lies inthe fact that. the flexible marginal iaps H will ive additional protection tothe tire in case 1t should collapse;

ing of the tire lfrom the tread, nevertheless, a 'collapse of the tiro mi ht occur through such causes as leakage at die valve o1- porous condition of the air tube. In such a case I there would be danger of injury to the tire 'bytheends vof the stri s. This danger is l,however avoided or' at qeast minimizedby fthe fact that in -case ofithe tires collapse, the flexible mar inal fis i ward so as to orm cus ions (see Fig. 2), which prevent the' shoe or the tube trom bestrips,'or by pressure u on the wheel rim.

embe ded also vform ,cushions in whic said lstrips are vinclosed and serve to protect fthe Thev metal plates of course, are suiiicientto prevent the punctur- H, will fold inric la 'ers etween which the metal stri vs are and shoe from in'ury by or other parts of the p a length materially lsheath the hinges G ates G.

"If desired, the stitches C, instead of eX- tending entirely across the rotector may terminate atthe rows of stitc es a.

1. A' tire protector comprising a flexible formed` with circumferentially adjaand the shoe o a pneumatic tire, flexible metallic strips of less tha-n the Width of the sheath contained-in said pockets, said strips being composed of short metal plates so hinged'end to end that each plate Will have free movement to either side of the comprising aflexible r vided with coacting hinge members on adjacent edges, said hinge members being so madey that each plate may swing freely to either side of the plane of the adjacent plate to. which it is connected.

4. A tire protector comprising a flexible sheath formed vvith pockets extending transtained 1n said pockets, each stri comprising a seriesof exibly connected plhtes and being of a length materially less than the Width of the protector, so as te leave at each side of the central portion which inclose's the strips a flexible marginal fla ,f i
